TeraRouting TesterTM Software Module
Spanning Tree Product Overview The Spanning Tree software module includes the emulation of Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP). This module supports STP/RSTP functional and performance tests for Layer 2 loop prevention and convergence. While the appropriate messaging is emulated, Layer 2 traffic can also be generated to verify the device under test’s port state and forwarding performance. Key Features n Allows spanning tree versions to be run concurrently with each other and with other protocols to test behavior in a realistic system environment n Simulates millions of unique Layer 2 hosts to populate the DUT ’s MAC address table n Provides real-time statistics and graphical result screen presentation to support accurate characterization of transient conditions n Control plane capture of transmitted and received protocol messaging, including export to protocol decoder for detailed troubleshooting and analysis n Event log to see detailed protocol exchange without capture and decode n Flap schedule events supported for functional and negative testing n Tests with Layer 2 and Layer 3 broadcast, unicast and multicast traffic n Integrated Layer 2 traffic wizard
